Filed: 1970-12-04
Abstract: 1293835 Preventing running on in I C engines; stop gear FORD MOTOR CO Ltd 4 Dec 1970 [12 Dec 1969] 57674/70 Headings F1B and F1K A spark ignition I.C. engine comprises a passage 24 supplying idling fuel to an induction passage 12 downstream of a throttle 14 and a "running-on" prevention mechanism in which air is transmitted from a container 30 to the idling passage when the ignition system is turned off so that the air reduces the idling fuel supply. Solenoid 62 is energized during normal operation so that valve rod 54 is magnetically held to lower seat 46. Intake manifold pressure via pipe 39 draws spring-loaded piston 32 to the position shown and the idling fuel is drawn from well 22 via jet 26, passage 24 and orifice 28 into the passage 12. When the switch 66 is opened to cut off the ignition circuit valve rod 54 is pressed on to seat 50 and the increased intake manifold pressure permits spring 37 to move piston 32 upwardly forcing the air in chamber 34 through passage 48 into the idling passage 24 where it reduces the fuel flow through jet 26 thereby stopping the engine. In a modification a check-valve is included in passage 52 and valve rod 54 moves on to only one seat.

Title: Engine performance analyzer using simulated load
IPC: G01L5/00
Filed: 1973-12-18
Abstract: 1450728 Engine performance analyzer RCA CORPORATION 18 Dec 1973 [30 March 1973] 58554/73 Heading G1N The overall performance of an I.C. engine under simulated load conditions is determined by adjusting the throttle to a desired high speed setting and inhibiting the ignition spark for selected cylinders whereby the engines behaves as though it is on load and attains a test speed which may be compared with a reference speed for that throttle setting to give an indication of the engine performance. As shown (Fig. 3), the voltage pulses across the circuit breaker 22 are fed via a pulse shaper 28 to a counter 30. The first, say four pulses produce a positive output pulse from an ignition control gate 32 which causes transistor 24 to conduct and form a shunt path to circuit breaker 22, thereby limiting the flux change in the ignition coil windings 16, 18 and preventing the formation of a H.V. ignition pulse for the sparkplugs. The fifth pulse from circuit breaker 22 resets the counter 30 and allows the formation of an ignition spark. Hence the engine produces only one fifth of its power for each throttle setting, and settles down to the speed at which this power is equal to the engine losses, and this speed is compared with a predetermined reference speed to provide an indication of the engine condition at that throttle setting. The apparatus includes interlock logic means 34 to ensure that the engine speed is allowed to go beyond the reference speed before the ignition pulses are selectively inhibited, and the engine is shut down if its temperature exceeds a pre-set value or if its speed exceeds a limiting value.

As shown, the cut-out comprises a feeler 4 pivoted by two pins 8 on an end of pivotable drum cradle 3 carrying wire drum 6. The relatively hard feeler portion 15 is urged against wire 7 by two torsion springs 5 which may be adjustable. When the wire breaks the feeler rises to move ferro-magnetic member 10, via arm 9 freely pivoted on pins 8, to lie adjacent a coil mounted on machine rotor 13. The current induced in the coil acts to cut out the machine drive and to operate machine brakes. The cutout also functions if cradle 3 rotates, the feeler being pivoted by centrifugal or gravitational force.

Abstract: 1,268,880. Protective arrangements. COMPAGNIE ELECTRO-MECANIQUE. 31 Dec., 1969 [31 Dec., 1968], No. 63436/69. Heading H2K. [Also in Division H1] A self-resetting relay comprises two levers 6, 7 pivoted together by a torsion spring 8 for relative movement when first arms of the levers are relatively displaced by current sensitive bimetallic elements but not when the first arms are similarly displaced, second arms of the levers carrying co-operating contacts 9, 10. The relay is a polyphase relay having bimetallic strips 1a ... 1c with free ends extending through apertures in insulating bars 3, 4 which move the lower, second, arms of the levers 6, 7 together to open the contacts 9, 10 when relative motion occurs between the bars 3, 4 due to unbalanced conditions in the currents heating the bimetallic strips. Relative motion between the bars also occurs under balanced overload condition when the bar 3 abuts an adjustable stop 5. The first arm of the lever 6 normally pivots about projections 11, 12 of a push-button 13 which has an inclined surface 15 so that depression of the push-button opens the contacts, the surface 15 engaging and moving the rounded end 16 of the lever 7. This enables the push-button to be used as a stop button when the relay is used to control the operation of a contactor. The relay may also  control an acoustic alarm.

IPC: B65D85/07
Abstract: 730,275. Packing spring assemblies. ELSON & ROBBINS, Ltd. April 10, 1952 [Feb. 20, 1951], No. 4066/51. Class 94 (1). In a method of packing a spring assembly, e.g. a mattress, pressure is applied to the assembly along parallel lines to cause it to fold in zig-zag manner and the folds are secured together. The folded assembly may be compressed to reduce its volume and a plurality of folded and compressed assemblies may be superimposed and fastened together to form a bundle. As shown, a mattress interior is placed on a horizontal support and compressed between adjacent rows of springs along parallel lines 3a and 3b by plates 5 held in position by catches 20 mounted to slide on rods 21. A plate 4 carried by a bar 10 is then moved upwardly by rack and pinion gearing 12, 13 actuated by a lever 11 to raise the central part of the mattress and at the same time the plates 5 are moved inwardly so that the mattress is folded in the manner shown. The movement of the plates is effected by an endless belt 22 coupled to the catches 20 and bar 10. The raising of the central part of the mattress may be assisted by a cross head 14 movable in vertical guides and urged upwardly by levers 16 and 17 loaded by springs 18 and 19. Grilles 23, 24 fitted with removable plates 7, 8 and pivoted to the catches 20 are then swung upwardly to fold the end portions of the mattress about the lines 3a and 3b and forced inwardly by levers 25, 27 and 26, 28 until the plates 7, 8 are retained by catches 29, 30, 31 and 32. The plate 4 and grilles are then returned to their original positions and after removal of the plates 5 the plates 7 and 8 are forced inwardly by cams 33 - 36 actuated by levers 37 - 40. The plates 7 and 8 are then secured together by temporary retaining pegs passed through holes therein and the compressed and folded mattress removed from the apparatus and transferred to a press. After further pressure has been applied, the plates are removed and the folds secured together by wire ties or other means. Alternatively a plurality of the compressed and folded assemblies may be superimposed in a press and, after compression and removal of the plates, secured together by wire ties to form a bundle. Modifications are described in the Provisional Specification.
